down sliding movement-and: in addition also Y permit the sashes to be swung on separate horizontal-pivots; that may be suspended by means of the usual cords and sash weights;

that may combine with the'otherfeatures the use of any desiredfform of weather strip at the top and bottom of thewindow and at the junction of the two sashes; that provides a permanent weather strip between the extra side stiles or auxiliary rails-of the sashes and the window frame edgewise of the sashes that also holds the sashes against thefstops or parting strips to seal'olf these vertical sliding surfaces in order to place friction.

against the sashes and at the same time prevent sash rattle; and that'w-hen desired the usual sash cords and weights may be omitted different positions in the window frame,v I lVith these and other ends in'view, I illustrate in the accompanying drawing such instances of adaptation as will disclosef'the broad underlying features ofmy invention without limiting myself to the specific details shown thereon and described herein 1 Figure 1 is an elevation of a window closed by two sashes.

which only a single vertical member is shown in the enlarged views, as obviously the other.

' show the sameapplied to a window frame 1 of 7 vertical member of the window frame isa duplicate. On the outer edgeof'the frame 1 the usual outside trim 2 is placed. This, hasan inside groove5-in which the guide 19, that is placed. It is substantially of right angled shape in cross section with a bead formed at the intersection of the two angles, so as to pro-- duce a groove 20 at this point. The flat por-' tion 21 of these guides is nailed .to the wins dow frame Between the'outside trim2 andthe inside stop 4 the parting strip 3 is 10- cated. It has'formed inits edges grooves 5 for receiving the guides 19 whichare fastened to the frame by their fiat faces 21% above mentioned. Inthe case of the parting strip guides one edge 22 is bent out slightly so as to form an :auxiliaryspring tension against the window sashes6 and28. Thisprovision, in connection with the friction of compression strips 16, may serve to hold the sashes in different positions in the window frame through the friction of their contacting surfaces.

The inside stop. 4 also is provided with a groove 5 in which a right angled guide 19 is placed. This is fastened to the frame in a similar way to the means used to hold the described.

The lower sash 6 function is -concerned. They are each pro- ,vid edwith auxiliary rails 8. Separate spring bronze. compression. strips 16' are attached to the outside edges of the auxiliary rails 8. These springstrips extend the length of each. sash. They arecurved .ase showniin Figs. 2

and 3, and are seated in a concave groove strips, inside stops, etc., will be hereinafter N g and theuppersas'h are v substantially duplicates of each other in "so far as the combined sliding and swinging 5 formedin the'railsf8 wherethey areheld by v screws 24.. The edges 17'ofthese compression strips 16-are slightly curved in a reverse di rection. from the center portion of the strips so as'toeasilyslide in'the grooves 20 of the guides 19; The outer edge of each sash rail has a lengthwise concavegroove 9 formed therein, 'and the auxiliary rails 8 have a cor- 65 i extends the full length of the window frame,

' responding head 10 formed on the adjacent pins 13, which are secured in pivot plates 7 held in recesses of the sashes by screws 25.

These pins pass through holes 12 of bearing plates 11 into corresponding openings formed inthe rails 8. The bearing plates 11 are attaehed'to the inner edge of the auxiliary rails or stiles 8 by means of nails 26.. The beads 10 and grooves 9 serve to hold the parts in sealed-off alignment with each other during such times the windows are merely. slid up and down in the window frame.

. lVhenever it is desired to swingthe window sashesso as to bring the outer surface of the glassinto the inside of the room for clean ing and washing, the sashes are swung on the pivot pins 13 and may be held at'an angle by reason of the beads 2230f the bearing plates 11 sea-ting themselves in the angular grooves 15 of the pivot plates 7'. If the sashes are to be simply turned at right angles to their usual position, the beads 23 will lie in horizontal grooves 1 1. 'Vllhen the sashes are in their normal vertical position tl e beads 10 engage the groove 9, and the'beads 23 engage the vertical grooves 29. of the pivot plates 7 where-they are held in ayielding relation by means of the spring compression strips 16.]

' There is suliicient clearance between the edges-17 of the compression strips 16 and the grooves 20 of the guides19 to allow free movement, as these compression strips 16 are put under tension whenever the sashes are to be swung on their pivot pins 13. On these occasions the beads 10 ride out of the grooves 9 and the beads 23 pass out of the grooves 29 as the auxiliary rails 8 are moved edge wise far enough to allow the beads 10 to ride on the plain'edges of the sashes. This edge-- wise movement of the rails 8 is against the compression strips 16, which movement is 'counteractedwby the compression strips as soon as tli'e'beads 23 are found opposite any one of the grooves 14, 15, or 29 of the pivot plates 7.

The upper and lower sashes may be assembled in the bare window frame 1 as follows: A full length guide 19 is placed with its bead in the groo-ve5 of the outside trim isplaced in th'e open space 18 'andthe one. 6.0

v 2 where it is fastened to the frame by means tire sash is .shoved into position towards the outside trim 2 by first holding inthe.

compressionqstrip 16. Then the companion guide 19 with its spr ng edge 22 is. shoved onto the edge .17 of ,the compressionstrip limits of the diagonal grooves 15.

16 as far as possible, after which the parting strip 3i is first inserted; in its groove atthe bottom end' of the frame 1 while the up per sash is in its raised position. The other guide 19 is next placed against the inner edge of the parting strip, the lower sash placed into position, theinside guide 19 pushed onto the edge of the compression strip and finally the inside stop 4 attached. The three inner guides 19 are nailed to the frame 1 by shifting the sashes into, their extreme positions.

It will be seen that my construction provides a very snug fit betweenthe auxiliary: rails and the guides. The parts-throughout, are very simple and beingmade of non-rusting materials are a most efficient and simple means-for producing much desired sliding and swinging window sashesf 1 As shown in theidrawing, Fig. 5, the diag:

renal grooves 15 extend'beyond the metal plate 7. In, practice, if desired, I may make the plate 7 long enough to extend beyond the m y make the plate .7 "as ametal stamping out of heavy gauge bronze material or instead a metallic'casting may be used if it is desired. In Fig. 7 thegrooves 5 would in practicebe made relatively deeper than'shownto whatever extent is found desirable. If this ,is done the parts. 19, 21 and 22, 21; would be made to lit the deeper grooves 5 and if necessary the stops 2 and especially the parting strips 3 can be made wider to accommodate the increased depth of the grooves 5. If found necessary nails may be used through the parting strips 3 inaddition to the nails. 27 which hold thefinetallic strips21, 22 in place. v V
